ROAD-DRAG Application filed. November 17, 1917.

To all whom it may concern:

Be it known that I, Josnrn S. Hours, a citizen of the United States, residing at Vihat Cheer, in the county of Keokuk, State of Iowa, have invented certain new and useful improvements in Road-Drags; and I do hereby declare the following to be a full, clear, and exact description of the invention such. as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in road drags.

One object of the present invention is to provide a road drag of such construction that the formation of small channels or ditches in the road is prevented.

Another object is to provide a road drag of such construction that the same may be operated in the manner of the ordinary drag or be adjusted to prevent the formation of the small ditches in the road surface. 7

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing. v

In the drawing:

Figure 1 is a top plan view of a road drag made in accordance with my invention.

Fig. 2 is a front elevation of the device.

Fig. 3 is a side elevation of the device.

Fig. at is an enlarged vertical sectional view taken on the line h-f of Fig. 2.

Referring particularly to the accompanying drawing, 10 represents the front board or blade of the drag, and 11 the rear board or blade, said blades being disposed in parallel relation and connected together by means of the beams 12. The lower corner of the front blade is cut away on an oblique angle, as shown at 13, while the corresponding corner of the rear blade is similarly cut away. Secured to the front vertical face of the blade 10, immediately above the cut away portion, is a triangular plate 15 the same being offset, away from the blade, at its inner edge, as shown at 16. Near the lower edge of the blade 10, and inwardly of the cut-away corner, there is disposed through said blade :1 bolt 17. Engaged on this bolt is a sleeve 18, and receiving this sleeve is an opening 19 formed in the inner end of the triangular plate 20. A washer 21 is engaged on the bolt and bears on the outer end of the said sleeve. A. nut 22 is engaged specification of Letters Patent.

on the bolt and bears against said washer, whereby the parts are held in proper position on the blade, and whereby the plate 20 is capable of free pivotal movement. The outer, or wider end of the plate 20 is arranged to slide between the blade 10 and the offset portion of the plate 15.

Mounted on the front board 10 is a vertical lever 23 the lower end of which is formed with an arm 2% which is pivotally connected to the wider end of the plate 20, by means of a link 25. A rack segment 26 is also mounted on the'beam 10 for engagement by the pawl 27 carried by said lever. Thus the plate 20 can be raised and lowered and held in such position.

In the use of the ordinary road drag one of the corners of the scraping blade digs into the surface of the road and forms a small trench. or groove which readily fills with water, when it rains, and the rain follows this groove rather than to drain into the ditches at the sides of the road. With the present device, by the raising of the pivoted plate 20, the cut-away corner will prevent this digging action, and the, surface of the road. be leveled without the formation of the before-mentioned grooves.

What is claimed is:

1. A road drag including a scraping blade, a portion of one of the lower corners of said blade being removed, a plate pivotally mounted on the blade for movement to cover and uncover the cutaway portion of the blade, and means for moving said plate.

2. A. road drag including a scraping blade, one of the lower corners of said blade being cut away on an oblique angle, a plate secured to the blade above the cut-away corner and having an offset inner portion, a triangular plate pivotally mounted on the blade and arranged to be moved to cover. the cut-away corner and form a continuation of the lower edge of the blade, the outer end of the plate being movable between the blade and the offset portion of the triangular plate, and means for raising and lowering said pivoted plate.

In testimony whereof I aflix my signature in the presence of two witnesses.
